When frying fish (or anything, really), it can stink up the house pretty fast. If you want to avoid that lingering smell, all you need is a spoonful of creamy peanut butter. As Howcast explains in the video above (around the 40 second mark), just place the creamy peanut butter in the pan while cooking and it'll absorb the smell while you cook.

At first I was a little confused because it seemed like the peanut butter would mix in with the frying fish, but after looking into this tip a bit further I found that it should mostly stay put if you keep it on the edge of the pan (kind of like the video shows). Other sites also suggested frying the peanut butter for a minute after cooking the fish to avoid that problem. There seems to be no concrete opinion on when the peanut butter should be fried to rid your house of fish smell, but it should do the trick so long as it happens during or after the frying process.
